Abstract. Aims. We present the catalogue of X-ray sources detected by the
two Wide Field Cameras (WFCs) in complete observations on board BeppoSAX
during its 6 years of operational lifetime, between April 1996 and April
2002. Methods: The BeppoSAX WFCs were coded mask instruments sensitive in
the 2-28 keV energy band with a 40x40 square degree fields of view,
pointing in opposite directions and perpendicularly to the BeppoSAX Narrow
Field Instruments (NFI). The WFCs were usually operated simultaneously to
NFI observations, each lasting up to several days. WFCs observed thus the
entire sky several times with a typical sensitivity of 2 to 10 mCrab. A
systematic analysis of all WFC observations in the BeppoSAX archive has
been carried out using the latest post-mission release of the WFC analysis
software and calibrations. Results: The catalogue includes 253 distinct
sources, obtained from a total sample of 8283 WFC detections. We describe
the basic statistical properties of the sample and present a six-year
history of two celestial calibration X-ray sources.
